View Upgrade Overview

<

Upgrading an enterprise View deployment involves several high-level tasks. Upgrading is a multistage process in which procedures must be performed in a particular order. You upgrade View Composer before upgrading View Connection Server and the other View servers.

During an upgrade, View does not support View Composer provisioning and maintenance operations. Operations such as provisioning and recomposing linked-clone desktops are not supported during the transitional period when any View servers are still running the earlier version. You can successfully perform these operations only when all instances of View Connection Server and View Composer have been upgraded.

You must complete the upgrade process in a specific order. Order is also important within each upgrade stage.

Note:

This overview relates to upgrades for major, minor, and maintenance releases. For information about patches, see Applying View Patches.

How many of the following tasks you need to complete depends on which components of View you use in your deployment.

After you upgrade a View Connection Server instance to the latest version, you cannot downgrade that instance to an earlier version. After you upgrade all View Connection Server instances in a replicated group, you cannot add another instance that runs an earlier version.

If you use security servers, upgrade each security server and its paired View Connection Server instance. If you upgrade these pairs one by one, removing each security server from the load-balanced group, upgrading the pair, and then adding the security server back to the group, you can achieve zero downtime. See Upgrade View Security Servers and Their Paired View Connection Servers.

Upgrade the Horizon™ View Agent™ software that runs on the physical or virtual machines that are used as desktop sources, as full-clone desktops in a pool, and as individual desktops in a manual pool. See Upgrade View Agent.

Because certain commands can simultaneously upgrade more than one stage, VMware recommends that you thoroughly understand the irreversible changes at each stage before you upgrade your production environments.

Important:

The VMware View® Client with Local Mode feature, for using offline desktops, has been removed, and therefore this overview does not include steps for upgrading View Transfer Server instances and View Client with Local Mode. In place of the Local Mode feature, VMware recommends using VMware® Mirage™, which is included with VMware Horizon 6.0 and later releases.
